CONTROL LEVER
Handle fuel with care! Use an approved fuel
container. DO NOT smoke near open fuel container
and keep fuel container away from open flame. DO
NOT fill fuel tank indoors or when engine is
running. Allow engine to cool for at least ten
minutes before refilling. Wipe off any spilled fuel
before starting engine. DO NOT run engine indoors.
Before attempting any adjustments, maintenance,
service, or repairs, stop engine and blade, always
remove key from ignition sw itch , remov e spark p lug
wire(s) and secure wire(s) away from spark plug(s).
STEP 12: MOWER DECK ADJUSTMENT (LEVELNESS)
SIDE to SIDE and FRONT to REAR
Before mak ing deck leveling adjus tments, inflate r ear tires
to 12 PSI and front tires to 25 PSI. When adjusted
correctly, the deck will be level side to side within 1/8”, have
a low cut setting of approximately 1” and the blades pitched
approximately 3/16” higher at the rear.
A. Place machine on a smooth level surface.
B. Check blade tips by rotating blades until tips are
pointing to the sides of the deck. Check the
measurement of outside blade tips to the ground on
both blades. The measurem ent of each of the outside
blade tips should be within 1/8” of each other. If
measurement of the blade tips is not within 1/8”,
adjustment should be made to the correct
measurement.
C. Move deck lift lever and set the mower deck to the
highest cutting position.
D. Relieve tension on deck lift assist spring by loosening
nut on eyebolt.
E. Place 1” blocks under the f ront and rear edge of the
mower deck.
F. Move deck lift lever and set the mower deck to a
lower cutting position until deck rests on the 1” blocks.
G. Loosen the nuts and bolts that secure both front
deck support chains. Adjust chains until tight and
retighten bolts and nuts. Torque to 70 ft. lbs.
H. Loosen the nuts that secure both rear deck support
eyebolts. Adjust to remove slack from both rear chains.
Tighten nuts securely.
I. Move deck lift lever and set the mower deck to the
highest cutting position and recheck side to side blade
tip dimensions. The dif ference between the two should
be 1/8” or less.
NOTE: The deck tim ing rod is preset at the factor y and
requires no adjustments.
J. The leveling blocks used in Step E should result in a
proper deck pitc h. If a pitc h adjustm ent is required, us e
the two rear deck support eyebolts. Adjust up or down
as required.
K. Reinstall deck lif t ass ist spr ing. Place deck in highest
cutting position. Tighten nut on eyebolt until 1 1/4” of
threads protrude past end of nut.
STEP 13: HYDRAULIC OIL RESERVOIRS
Check the level of the fluid in both of the fluid reservoirs. The
reservoirs are loc ated underneath the operator’s s eat. W ipe
away all dirt and debris from around reservoir cap before
removing. Oil must remain absolutely clean! Check with
machine on a level surf ace with engine “OFF”. Fill res ervoir
as needed to bring level up. The res ervoir is properly filled
when the fluid level is 1½” below the top of the filler neck. DO
NOT OVER FILL. Use clean, fresh prem ium automotive oil
having a viscosity equivalent to SAE 20W50 API SL. The
fluid should be chemically stable, incorporating rust and
oxidation inhibitors. Make sure funnels, pouring spouts and
oil can are completely clean. Reinstall reservoir cap.
IMPORTANT: Re-check fluid level after operating machine for
several minutes and adjust level as needed. If one or both of
the wheel drive systems is not pulling properly, the hydraulic
system may need to be purged of entrapped air. Refer to
STEP “HYDRAULIC SYSTEM, PURGING”.
STEP 14: TRACKING ADJUSTMENT – TWIN STICK
CONTROLS
Start machine. If the m achine does not track straight when
the Motion Control Levers are in the maximum forward
speed position, perform the f ollowing adj ustment. Rear tire
pressure must be set to 12 PSI before making this
adjustment.
A. Loosen bolts that secure adjustment plates and slide
plates all the way forward. Retighten bolts.
B. Start machine and drive in smooth flat open area at
maximum forward speed.
C. If machine tracks to the right, loosen bolts that secure the
left adjustment plate. Move plate rear ward to slow the left
wheel. Retighten bolts.
D. If machine tracks to the left, loosen bolts that sec ure the
right adjustment plate. Move plate rearward to slow the
right wheel down. Retighten bolts. See Figure 2.
E. Drive machine again. Repeat adjustm ent as necessary
until machine tracks straight.

STEP 15: HYDRAULIC SYSTEM, PURGING
After replacing or repairing hydraulic system
components, one or both of the wheel drives may
not pull properly. This is likely to be caused by air
entrapped in the system. If you experience a
pulling issue after completing repairs or during
initial setup, perform the following procedure to
purge the air from one or both of the hydraulic
drive systems.
IMPORTANT: WHEN REPLACING THE HYDRAULIC
FLUID FILTERS, PRE-FILL BOTH WITH OIL
(SAE 20W50 AP I SL) BEFORE INSTALLING.
PRE-FILLING THE FILTERS WITH OIL WILL
REDUCE OR POSSIBLY ELIMINATE THE NEED
TO PURGE THE SYSTEM OF ENTRAPPED AIR.
A. Locate hydraulic reservoir underneath
operator’s seat. After thoroughly cleaning the area
around the top of the reservoir, remove filler cap.
Bring fluid to proper level (1 ½” below the top of
the filler neck). With engine off, add SAE 20W50
automotive oil. See Figure 3.
B. Open pressure relief valve on hydraulic pump,
turning counter clockwise 2 full turns. See Figure
4.
C. Carefully raise the rear of the machine so the
wheels are off of the ground. Securely block the
machine to prevent it from falling.
D. While seated in the operator’s position, start the
engine. Place engine speed control in FAST
position.
E. Release parking brake and move motion
control levers out of the neutral lock position.
F. Slowly move motion control levers to the full
forward and then to the full reward positions.
Repeat this process 6 times.
G. Stop engine and wait for all rotation to stop
before leaving the operator’s position.
H. Close pressure relief valve on hydraulic pump,
turning clockwise. Tighten snuggly.
I. With pressure relief valve closed, repeat Steps
4 thru 7.
J. Remove blocks and lower rear of machine.
K. Check fluid level in reservoir. Add SAE 20W50
automotive oil as required to bring fluid level to 1
½” from top of filler neck. Do Not over fill.
L. Install and tighten filler cap.
